Every Gauge quit working

I have a 1999 Oldsmobile Alero. I was driving down the street,
coming to a stop sign and looked at the speedometer because I felt I
was going a little fast for the stop. As I was coming to a stop,
looking at the gauges, every single one went to zero.. as if the car
was off. I continued to drive the car to my home, with no clue on how
fast i was going, how much gasoline I had or what temperature the car
was. The light on the gear indicator went off, and the miles do not add
anymore. Every single light that could turn on in the dash ( Traction,
ABS, Security, Coolant, Battery, Service Engine Soon, and Check
Engine), turned on when the gauges dropped to zero.
When I got home and turned the car off, I took the key out of the
ignition and the odometer stayed on. Along with the battery light on
the far right side of the instrument panel next to the speedometer.
Every other light went off. It seemed as if the starter was still
engaged. So I popped the hood, and unplugged the positive from the
battery. I went to sleep as it was night time.
The next day I plugged the Positive back into the battery, and
turned the car on. All of the lights that were on the day before had
gone off, except for the battery and the odometer. I drove the car like
this for a couple of days.
All of a sudden, another situation as when it first occured, I went
to look at the speedometer thinking it worked, trying to figure out how
fast I was going, and the car chimed three times, and the gauges
started to work again. It started to read miles and only had the
security light and traction off light on.
If someone has any clue what this might be, please help. I am in
DESPERATE need of some sort of help, as I have absolutely no idea.

I appreciate your work, Jeremy.

P.S. - I went to Auto-Zone and had my alternator checked, it was strong.
- I checked every fuse in the car.
- Cannot check every relay... would not have a clue which relay it would be.
- Tried to have auto zone diagnose from inside the car, came up with no codes.

Your BCM may have gotten wet. It's in the area of the glove box. My window leaked and got mine wet. Lost all gages, lights wouldn't turn off. I unplugged it, opened it up and allowed it to dry overnight. When i plugged it back in in the am, it worked fine. I sealed up my window and haven't had it happen agsinYour BCM may have gotten wet.

use a scanner to check the abs system . most of the time the abs brakes and traction control system work together. your cruise control . unit has a servo motor .in front right fender well. check the fuse and relay also the cruise control brake release switch. and the brake light switch.if all is good you have a cruise control module problems. dealer ship job.

I am assuming its not the service engine soon light it is probably the service vehicle soon light, There are 2 lights service vehicle soon upper left side, and service engine soon upper right side.

When all these come on at the same time it is the wheel bearing sensor. Usually the wheel bearing needs to be replaced which houses the sensor. A sure way to check is to press your sls button by your shifter and see if the light goes out, If it does not, u will need to have a wheel bearing put in.

LOOK FOR ETS BUTTON ON THE CENTER OF THE CONSOLE.THE INDICATOR LIGHT WILL TURN OFF BUT LONG AS CURRENT NEED TO LIMIT WHEEL SPIN THE TRAC LIGHT WILL REMAIN ON.TAKE VECHICLE TO GARAGE OR DEALERSHIP.HAVE THEM SCAN THE ABS AND TRAC CONTROL SYSTEM.MOST OF THE TIME A BAD WHEEL SENSOR WILL SET OFF TRAC WARNING LIGHT.

check the fuses. they are under the back seat just pull up on the lower part of the back seat and it will come out. fuse box is on the drivers side. check to see if water is getting in that could be the cause.

Could be lose connection on the back of the instrument cluster ,which means you would need to pull it out of the vehicle . Check pin fit to instrument cluster . for the B+ voltage suppy an ground connection's .
You said autozone - Tried to have auto zone diagnose from inside the car, came up with no codes. That's in the PCM - engine computer . There scan tool will not communicate with the instrument cluster ,which is also a computer in it's self. Need a factory scan tool to check instrument cluster.

well # 1 the full gauge when empty is a sign that your fuel pump is bad and that needs to be replaced the part about spitting the gas back out is probrobly a clog between the fuel door and the tank itself or their might be a vapor lock door that might be stuck shut so fuel cant get in im not 100%sure about that but im 100%sure that the fuel guage is the fuel pump being dead.

I replaced the radio with an aftermarket one and now my dash lights, power windows and my headllights have dont come on automataclly like they did before. my alarm on my remote dont work either, I think i did something to the alarm system, that is why they are not working.
